Description
The CHM2179b is a single channel mixer. The structure is a balanced mixer based on a six-quarter wave ring. The non-linear devices are high quality Schottky diodes providing low conversion loss and very low 1/f noise.
This circuit is manufactured with the BESMMIC process: 1 µm Schottky diode device, air bridges, via holes through the substrate, stepper lithography.
